v0.7.5 - Crash recovery, pane chrome, and ticker opens

Highlights

• Desktop startup and renderer crashes now land on an interactive recovery screen instead of a static dead window.
• Native pane chrome occlusion is tighter, so menus and command panels mask only the UI they actually cover.
• Holder treemap labels are more readable across themes.
• Market mover rows now open resolved ticker detail panes instead of empty detail views.

Changes

Desktop Recovery

• Added fatal recovery UI with restart, reload, and copy-error actions for renderer and startup failures. #366
• Added bootstrap fallback actions before React mounts, giving RPC startup timeouts a recovery path. #366

Pane Chrome and Tables

• Scoped native occluders for command bar and pane menus to their actual panels. #367
• Reserved terminal dock divider gutter space so pane footers and status rows remain visible. #367
• Improved holder treemap contrast by blending tile text toward the highest-contrast fallback. #367

Ticker Navigation

• Resolved ticker records before opening market mover detail panes. #368
• Reused the shared ticker open path across market movers, pinned ticker opens, and ticker navigation while preserving source-pane replacement behavior. #368
